RAS syndrome

Human language includes redundancy so that the brain can fill in gaps when something is misheard.
Sometimes this redundancy gets in the way of rapid communication, causing people to make an abbreviation.
But because there are only so many letters in the alphabet, sometimes these abbrevations can "collide", or have multiple independent meanings.
Speakers may disambiguate the meaning by reintroducing a generic term following the abbreviation.
The traditional use of trademarks as adjectives encourages this behavior as well.
Still, some pedants consider this use of "RAS syndrome", or "redundant abbreviation syndrome syndrome", as poor style.
